A user has requested a DVD-ROM drive be added to their desktop PC so they can watch videos sent in by vendors. You only have a Blu-Ray player in inventory. Is it likely you deploy this to the user and meet their requirement?
The Blu-ray specification recommends but does not require backwards compatibility with DVDs. However in practice most Blu-Ray drives are backwards compatible with DVD discs and can play their content. You should check to be completely sure, but it is true that the likely scenario is your Blu-ray player will support DVDs.
The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc storage format. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Wii U, Xbox One, and Xbox Series X.

Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives.High-definition (HD) video may be stored on Blu-ray Discs with up to 1920×1080 pixel resolution, at 24 progressive or 50/60 interlaced frames per second. DVD-Video discs were limited to a maximum resolution of 480i (NTSC, 720×480 pixels) or 576i (PAL, 720×576 pixels). Besides these hardware specifications, Blu-ray is associated with a set of multimedia formats.
